چکیده

هدف تحقیق: هدف از این تحقیق بررسی اثر فعالیت ورزشی بر اشتها و انرژی دریافتی در زنان با وزن طبیعی و دارای اضافه وزن بود.روش‌ تحقیق: هفت زن با وزن طبیعی (20>BMI>25) و 7 زن دارای اضافه وزن (25>BMI>30) غیر فعال (میانگین سنی 68/1±28/23 سال) در یک پروتکل 6 روزه نیمه تجربی شرکت کردند. دو روز اول به عنوان شرایط کنترل بدون فعالیت ورزشی در نظر گرفته شد. در روز 3 و 4 از آزمودنی ها خواسته شد تا به مدت 1 ساعت با شدت 60 درصد حداکثر ضربان قلب ذخیره روی نوارگردان بدوند. دو روز بعدی به عنوان شرایط پس از فعالیت در نظر گرفته شد. آزمودنی‌ها غذای مصرفی خود را در طول هر شش روز وزن کرده در برگه روزانه ثبت کردند. اشتهای آزمودنی‌ها هر روز صبح با مقیاس دیداری ثبت شد. نتایج: در زنان وزن طبیعی، میانگین انرژی دریافتی در روزهای پس از فعالیت (60/336±42/1498 کیلوکالری) به طور معنی­داری پایین تر از روزهای فعالیت (61/342±14/1897 کیلوکالری) بود (01/0>p). اما در زنان دارای اضافه وزن، انرژی دریافتی نسبی به طور معنی داری در روزهای فعالیت کمتر از روزهای کنترل بود (05/0>p). تفاوت معنی داری در ترکیب غذای مصرفی بین شرایط مختلف مشاهده نشد و تغییرات اشتها در بین روزها معنی دار نبود. اثر تعاملی گروه نیز در هیچ یک از متغیر ها معنی دار نبود. نتیجه­گیری: در مجموع، فعالیت با شدت متوسط موجب ایجاد تعادل منفی انرژی در زنان دارای اضافه وزن می شود و این نتایج نشان دهنده اثر مطلوب ورزش بر کنترل وزن در زنان دارای اضافه وزن است.

Effect of exercise on appetite and energy intake in normal and overweight women

چکیده [English]



Purpose: The purpose of this study was to determine the impact of exercise on appetite and energy intake
in normal and overweight females. Method: Seven normal weight (20<BMI<25), and 7 overweight
(25<BMI<30) inactive women (mean age 23.28 ±1.68) participated in a 6-days semi-experimental study.
First 2 days were assigned as control with no exercise. On the third and fourth days, participants were
asked to run on a treadmill at 60% maximum heart rate reserve for 1 h. Others subsequent 2 days were
consider as post-exercise days with no exercise. Subjects recorded dietary intake using a food diary and
self-weighed intake during each 6 days. Visual analogue scale (VAS) completed at each morning in
fasted state. Results: In normal weight women, average energy intake significantly reduced on postexercise
days (1498.42±336.60 kcal) compare with exercise days (1897.14±342.61 kcal) (p<0.01).
However, in overweight women, relative energy intake significantly reduced in exercise days compare
with control days (p<0.05). There was no significant differences in food compositions across conditions
in both groups and differences in appetite rate were not significant across the days. Interaction effect
between two groups was not significant in all variables.
Conclusion: In conclusions, moderate intensity exercise can create a negative energy balance in
overweight women. This result indicated a favorable clinical implication of exercise on weight control in
overweight women.
